S2 Centralizer

In 2001 Centek group revolutionized centralizer design and introduced the radically different S2® centralizer. Over the years the patented S2® bow spring centralizer has repeatedly proved to reduce failures - saving operators time and cost getting to total depth.

Simply Smarter

The non-welded, one-piece construction means the S2 has no weak points making it ultra-high-strength. It is designed specifically to replace a solid body type centralizer for casing running applications and severe well geometries when run in horizontal, long ERD, J-type, S-type and other well designs.

The S2 is manufactured to gauge and has exceptional restoring force and outstanding flexibility down hole. The S2 bow spring centralizer offers:

Optimum standoff capability in even the most challenging well conditions.

Enhanced rotation and reciprocation during cementing due to optimized centralization.

Award winning innovation

Over the years the S2 has received a number of awards including the prestigious Queens Award for innovation.

Shale Production

The Centek S2 has been an integral part of the success of US Shale play production. Working within some of the world’s toughest regulatory guidelines, the S2 provides excellent centralization, and fluid circulation required to give a robust cement sheath, which in turn ensures the integrity, production and overall life of the well.
